Answer:

$z=\frac{0.05 -0.06}{\sqrt{\frac{0.06(1-0.06)}{97}}}=-0.415$

Now we can find the p value with the following probability:

$p_v =P(z$

Step-by-step explanation:

Information given

n=97 represent the random sample taken

$\hat p=0.05$ estimated proportion of defective

$p_o=0.06$ is the value to verify

z would represent the statistic

$p_v$ represent the p value

Hypothesis to tests

We want to tet if the true proportion is less than 6%, the system of hypothesis are:

Null hypothesis: $p\geq 0.06$

Alternative hypothesis: $p < 0.06$

The statistic is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing the info given we got:

$z=\frac{0.05 -0.06}{\sqrt{\frac{0.06(1-0.06)}{97}}}=-0.415$

Now we can find the p value with the following probability:

$p_v =P(z$
